Overheating or an oil-pressure warning while the engine is running? Pull over safely, switch off the engine and arrange professional assistance. If braking ability is reduced, stop safely and arrange assistance rather than driving to the shop.

Mechanical expertise, explained clearly
More than a list of parts to replace
Your symptoms are the starting point. What we find during inspection and testing is what shapes the repair recommendation.
Engine & electrical diagnosis
Find the cause before choosing the repair
A check-engine code tells us where the vehicle has detected a fault; it does not, by itself, establish which part needs replacing. Tell us whether the problem happens on a cold start, after the engine warms up, under acceleration or only occasionally, and what has already been repaired.
Inspection and targeted testing help separate engine, fuel, ignition and electrical concerns. For oil leaks or suspected internal damage, the findings guide the discussion about repair options and whether major work is justified. A repeat no-start also needs a look beyond battery replacement: charging performance, connections and unwanted electrical draw may be involved.
Car A/C & engine cooling
The details of when it happens matter
Does the air stay cold on the highway but warm up at stoplights? Is airflow weak, or has cooling faded again after a recharge? Those details help us choose the checks. Depending on the concern, A/C diagnosis can involve leak testing, airflow, compressor operation, cooling fans and electrical controls. The findings guide whether refrigerant service or a repair is appropriate.
Engine overheating is separate from warm cabin air. Coolant loss, hose or radiator leaks and other cooling-system faults need their own assessment. Tell us about rising temperatures, prior overheating and recent cooling-system work. Las Vegas heat can expose a problem; it does not identify the failed component.
If it is overheating: pull over safely, switch off the engine and arrange assistance. Never remove a coolant cap while the engine is hot.
Have a warning light, noise or estimate you want explained?
Tell our team what happens, when it happens and what has already been tried.
Brakes, steering & suspension
Understand what needs attention
Brake noise or vibration does not mean the same pad-and-rotor job for every vehicle. Pad wear, rotor condition, caliper operation and hydraulic concerns can change what is needed. We explain the components involved so you can compare estimates on the same repair scope.
Pulling, clunks and uneven tire wear need a wider look at tires, steering and suspension. Wheel alignment changes the angles of the wheels; it will not repair worn or damaged parts. We offer suspension and steering repairs and wheel alignment, with the work based on what your vehicle needs.
Transmission & maintenance
Match the work to the findings
A transmission that slips, shifts harshly or hesitates before engaging needs diagnosis before a repair plan. Mechanical wear, fluid-related concerns and electrical or control faults can produce overlapping symptoms. A fluid service is not an automatic fix, and a symptom alone is not enough to recommend replacement. Bring any previous findings or estimate so we can explain the options.
For routine maintenance, we use your mileage, service history, vehicle condition and manufacturer’s guidance. Explore vehicle-specific fluid maintenance and scheduled maintenance planning. We help separate service that is due from a current fault, so you know what you are approving and why.
Independent Tesla mechanical service
Tesla service at two Las Vegas locations
Universal Motorcars provides Tesla mechanical service at Spring Mountain and Post Road. We help with A/C, brakes, suspension, steering and wheel alignment, plus selected low-voltage and cooling-system concerns. Internal high-voltage battery-pack repair is a separate specialty.
Tell us the model, year, symptoms and any recent repairs. Service scope and procedures vary by vehicle and findings; our team will confirm the right location before your visit.
From the first call to pickup
A repair plan you understand
Before work begins, you should understand what the inspection found, what the estimate includes and which decisions need your approval.
- Tell us what is happening.Share your vehicle details, symptoms, warning messages and recent repairs.
- Plan the inspection.Confirm availability, diagnostic charges, what the initial assessment covers and expected timing.
- Review the recommendation.Discuss the findings, repair priorities, parts and labor, estimate, timing and applicable warranty before authorizing work. Ask what any further testing would involve.
- Leave with a plan.At pickup, review the completed work, warranty documents and maintenance to plan next.
Considering a major repair?
Bring your dealership or repair-shop estimate and any diagnostic results. We can compare the findings, repair scope, parts, labor and warranty. A second opinion may confirm the original diagnosis or identify another repair path. Confirm diagnostic charges before inspection.

These guys were so kind. We didn't have an appointment (we were driving through Vegas on our way to Arizona), but they were willing to look at the car immediately and resolve our problem.

This place has amazing customer service! Submitted estimate request online, got a call within 30 minutes, and someone quoted it on-site as soon as I got there same day!! They went completely above and beyond, and were so friendly 😀 and professional. HIGHLY recommend! Not all autobody shops are created equal. Bonus: didn't have to go thru a national call center to speak to someone...they are local!!

A few useful answers
Ask us about your vehicle, the inspection and the repair options. We’ll help you understand the next step.
What vehicles do you service?
Our Spring Mountain shop handles mechanical repair and maintenance for domestic, Asian and European passenger vehicles. Call with the year, make, model and requested work so we can confirm availability. Tesla mechanical service is available at both Spring Mountain and Post Road; see our Tesla service page for vehicle and service coverage.
How much will diagnostics and repairs cost?
Costs depend on the vehicle, required testing and repair scope. Confirm diagnostic charges before inspection. We explain the findings, estimate, repair priorities and expected timing before you authorize repairs. A final repair estimate may require inspection and testing.
Can you review another shop’s estimate?
Yes. Bring the written estimate, diagnostic results and service history. We can inspect the vehicle and explain whether our findings support the recommended work. A second opinion may confirm the original diagnosis or identify another repair path. Confirm diagnostic charges before the inspection.
How long will the repair take?
Timing depends on the diagnosis, work required, parts availability and our schedule. Call with your vehicle details and symptoms to discuss assessment availability. We will discuss the repair timeline after diagnosis; same-day service is not guaranteed.
Is my appointment booked when I submit the form?
An online form is a service request. Our team needs to confirm your appointment, location, diagnostic charges and next steps. Include your vehicle’s year, make, model, mileage, symptoms and recent repairs. For Tesla service, include your preferred location.
When should I stop driving?
If the vehicle is overheating, braking ability is reduced, a major leak develops or an urgent safety warning appears, pull over when it is safe and stop driving. Arrange professional assistance rather than continuing to the shop. Describe the symptoms when you call.
